DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 and 2 thereof, a new and improved garden protection device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, it will be noted that the unit 10 essentially consists of a control head 11; a conventional sprinkler head of either the fixed or rotary type 12 having an adjustable area spray (shown in broken lines); a mounting post 13 for the control and sprinkler heads; and a garden hose 14 (shown in FIG. 2 in broken lines) for introducing water into a fitting on control head 11. A 110 volt power cord connection 15 for control head 11 (also shown in FIG. 2) is required as explained in connection with FIG. 3.

Referring now to FIG. 3, a sectional view of the control head 11 is shown. The actuating element for the sprinkler head 12 is a motion detecting sensor 17 mounted in the upper portion of control head 11. Mounted within sensor 17 is a conventional timer (not shown) which will deactivate the sensor 17 after a short interval, e.g. two or three minutes. The sensor 17 is connected to a conventional plug-in power source by power cord 16. Running from sensor 17 are a pair of electrical wires 18 connected to the terminals 19 of a solenoid valve unit 20. The spring loaded plunger 21 of solenoid valve 20 runs through a pair of seals 22 protecting the solenoid unit 20 from contact with water fed into the control head 11 through fitting 15 from the hose shown in FIG. 2. Shown in its open or actuated position in this FIG. 3, with the plunger 21 retracted, water from fitting 15 flows into the control head 11 and out through an outlet conduit 23 to sprinkler head 12. When the timer operates, plunger 21 drops and engages with the inlet end of conduit 23 closing off water flow to such sprinkler head 12 until the next time sensor 17 is activated and in turn activates the solenoid unit 20.

FIG. 4 illustrates in a sectional view the connection of outlet conduit 23 to the support or mounting post 13. Preferably post 13 is composed of threaded segments which may be increased or decreased in number to adjust the above ground height of the sprinkler head 12. The upper segment 27, as shown in FIG. 4 has a conduit 25 therein, open at its upper end 26 where it threadably connects to sprinkler head 12 (not shown in this view) and closed by a plug at its lower end where it connects with the lower segment section 24. The conduit 25 has a threaded connection 28 extending from and open to conduit 25 for connection with the outlet conduit 23 from the control head 11. When the solenoid unit in head 11 opens, water flows through outlet conduit 23 into conduit 25 and thence to sprinkler head 12.

FIG. 5 illustrates the lower segment section 24 having a pointed ground penetrating end portion for post 13. As mentioned above, the number and/or length of intermediate segments may vary depending upon the above ground height desired for sprinkler head 12.

Preferably, the support post 13 and conduits associated therewith are made of high impact plastic material as is the housing for control head 11. The lowest segment section 24 of post 13 may be made of steel to give greater strength to its pointed end if desired.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a garden protector and more particularly pertains to a device which may be used to scare off animals from an area under protection without damage to such animal.

2. Description of the Prior Art

The use of automatically activated water sprinklers is known in the prior art. More specifically, such devices heretofore devised and utilized for the purpose of automatically turning the sprinkler on are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. Such devices are utilized primarily for watering a lawn or garden at preset times although U.S. Pat. No. 4,253,606 differs in that it turns a sprinkler system on when the humidity in the soil reaches a predetermined low point. Other devices operating off timers are shown in U.S. Pat. Nos. 5,074,468; 3,865,138; 3,669,352; and 3,599,669.

In this respect, the device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of turning a sprinkler on only when the need to scare off an intruder in a protected area exists. Such a device eliminates danger of injury to a child or animal such as may occur when other types of devices such as electric fences are used for area protection.

Therefore, it can be appreciated that there exists a continuing need for new and improved sprinklers which can be used as protective devices. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of protective devices now present in the prior art, the present invention provides an improved construction wherein the same can be utilized to safely protect a garden against animal intrusion. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved garden protection apparatus which has all the advantages of the prior art devices and none of the disadvantages.

To attain this, the present invention essentially relates to a device for preventing damage to a garden, flower bed, ornamental tree or the like from wandering animals which comprises a water sprinkler head or heads designed to spray water over the area to be protected and activated by a motion sensor which detects intrusion of an animal into such area. The sudden shock of the water spray will drive off the animal without injury and a preset timer will cut off the spray after a brief interval.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
